2001 had three comics, and MNOG. MNOG wasn't the primary story, it was the only story.
Define "flashy and vibrant" then. Because they were certainly colorful, arguable more than G2, which used a lot of silver.
G1 had masks of power
G2 had masks of power
G3 has masks of power
If you're point is that G2 and G3 have reused and new masks of power, then yeah... because G1 didn't have anything TO draw from.
Not yet, no, but considering how much they like MNOG, they very well might.
The Shadow Matoran do not count, because they weren't people who willingly chose to follow Makuta, they had their minds corrupted.
A story is what it shows, not what it tells. You remember seeing the building tension between the several Metru leading up to the war? You remember how cool it was to see the Matoran fighting against each other, weaponizing the various Rahi, fighting with their limited elemental powers? You remember seeing the horror of the war leaders, trapped in the archives, with the Rahi set loose upon them? No? That's because no story ever portrayed those events. The Mutran Chronicles briefly mentions it, and that's it.
Y'know, fair point, I'll give you that. I'm so used to thinking of Teridax as just another Makuta, but his portrayal was very deity-esque in the early days.
Frozen in time, I mean.
